Ontario, CA sits in the heart of Orange County, a region that blends the innovation of the Greater Los Angeles tech corridor with a more affordable lifestyle. The city’s proximity to major hubs like Irvine, Santa Ana, and the bustling downtown Los Angeles area means tech talent can tap into a diverse ecosystem of startups, established firms, and research institutions while enjoying a lower cost of living. The presence of the Ontario International Airport further fuels a strong logistics technology sector, attracting companies that need real‑time data solutions for freight and supply chain operations.

Tech companies in Ontario span several verticals. Software and web development firms such as Adobe’s regional office and Oracle’s Irvine branch thrive here, alongside biotech innovators like Genentech’s Orange County lab and Life Sciences Park startups. The city also hosts hardware manufacturers, including Intel’s manufacturing plant in nearby Santa Ana, and telecommunications leaders like T‑Mobile’s Orange County headquarters. With the University of California, Irvine nearby, research collaborations and talent pipelines flow directly into local tech teams.

Ontario’s median rent hovers around $2,500 a month, significantly below the $3,500 average in central Los Angeles, but salaries for tech roles have been rising to match the talent demand. Salary transparency is therefore essential for candidates to negotiate competitively and for employers to attract the best talent. Knowing the exact pay range for roles such as software engineers, data scientists, or product managers helps job seekers evaluate whether a position aligns with their financial goals and lifestyle needs.
